Do you have a reproducible example that can be used to verify whether this is a problem for all .12 CakeQOS users? If not, please flash back to .12 and try to find one. Because if we don't get this, it will likely not be fixed in .13 ....+I also had issue with 386.12 on my AC86U, more than just 2-3 a day for me. Whenever I'm watching Twitch or I think it happens to some other video streaming services too, I got frequent buffers. Tried to rollback to 386.11, didn't face such issue. I only use Cake-QoS Merlin, no other add-on.
And to other readers of this post:
Can anybody else please confirm or dismiss whether they've had the same experiences with .12 and CakeQOS enabled with respect to what's being described by Sicario above^? And if you do experience it, please try and produce an example that other users in here can verify.
